Here, too, the "eyes" signify the understanding of truth and belief in it; so "to see" signifies to understand and believe, and the "ears" signify obedience, thus a life according to the truths of faith, and "to hear" signifies to obey and live. For one is blessed not because he sees and hears, but because he understands, believes, obeys, and lives. In the same, "The lamp of the body is the eye; if the eye be sound the whole body is light, if the eye be evil the whole body is darkened. If, therefore, the light . . . be darkness, how great is the darkness" (vi. 22, 23). Here, again, the "eye" signifies the understanding of truth and belief in it, which is called a lamp from the light of truth that man has from understanding and belief. And because a man becomes wise from understanding and believing in truth, it is said "if the eye be sound the whole body is light." The "body" means the man, and "to be light" means to be wise. But it is the reverse with the "evil eye," that is, understanding and believing in falsity. "Darkness" means falsities, "if the light be darkness" signifies if the truth be false or falsified, and because truth falsified is worse than any other falsity, it is said, "If the light be darkness, how great is the darkness." These few examples make clear what correspondence is and what influx is, namely, that the eye is a correspondence of the understanding and faith, the heart a correspondence of the will and love, the ears a correspondence of obedience, the lamp and light correspondences of truth, and darkness a correspondence of falsity, and so on; and as the one is spiritual and the other is natural, and the spiritual acts into the natural and forms it to a likeness of itself that it may appear before the eyes or before the world, so that action is influx. Such is the Word in each and every particular. (A.E., n. 1081.)
